Title: Improvements in or relating to tea-processing machines
IPC: A23F3/12
Filed: 1962-05-18
Abstract: 1,007,776. Processing tea. H. C. ANDREWS. May 18, 1962 [May 22, 1961], No. 19248/62. Heading A2B. An improved C.T.C. machine for processing tea, Figs. 1, 2 and 5, comprises a pair of rotatable, substantially parallel, e.g. horizontal, shafts 1 and 2, a plurality of outwardly tapering discs 3 mounted on each shaft, so that the discs on one shaft mesh with the discs on the other shaft, and a plurality of tongues or pressure plates 4, which project, from one side of the shafts, into the spaces between the discs where they are in mesh The frusto-conical faces of the discs and the co-operating faces of the tongues are adapted to effect a twisting, tearing and/or cutting action on leaf tea passing between said faces. The shafts 1 and 2 may be rotated, in opposite directions and at different speeds, by gears. According to a preferred construction, shaft 1 is rotated, anticlockwise, at a slower speed, e.g. 40 r.p.m., than shaft 2, which is rotated clockwise, e.g. at 60 r.p.m. The shaft 1 is journalled in bearings fixed to diagonal beams at each side of the machine frame. The shaft 2 is journalled in bearings at the lower ends of two arms 21 secured, at their upper ends, to a shaft 22 journalled in bearings on upper beams of said frame. Two tensioning bars 23 are pivoted, at 24, to the arms 21 and carry tensioning springs 25 and nuts 26. The bars 23 also carry stop nuts 27, for maintaining a desired clearance between the discs of shaft 2 and shaft 1. The tongues 4 are bolted together to form a pressureplate assembly 5, located below the shafts. The assembly 5 is slung between two arms 6 pivoting on the shaft 1 and pivotally connected, at 9, to two tensioning rods 8 carrying tensioning springs 10 and nuts 11. The rods 8 also carry stop nuts 12, for mantaining a desired clearance between the tongues and discs. The frusto-conical faces of the discs carry projections or battens, e.g. arranged as shown in Figs. 8 and 9, those on the discs of shaft 2 having sharp or rounded edges facing in the direction of rotation, and those on the discs of shaft 1 having sharp or rounded edges facing opposite to the direction of rotation. The faces 4alpha of the tongues 4 co-operating with discs on shaft 2 carry battens, e.g. arranged as shown in Fig. 7, and the faces 4b co-operating with discs on the shaft 1 are substantially smooth. Leaf tea, e.g. withered leaf, is fed between the discs by a travelling conveyer belt 28.

Title: Improvements in or relating to the securing of railway rails
IPC: E01B9/48
Filed: 1952-07-30
Abstract: 715,866. Securing railway rails. UNITED STEEL COS., Ltd., and MASON, B. G. Sept. 2, 1953 [Ju]y 30, 1952], No, 19282/52. Class 104 (2) A railway rail is secured to a metal sleeper or bearing plate by at least two spring clips each clip having an extension for insertion into a hole in the sleeper or plate and a nose piece and the arrangement is such that as the clip is rotated from its position of insertion in the hole to a position in which the nose piece bears on the rail flange the nose piece is stressed and guided on to the rail flange by an inclined surface on the sleeper or plate and means are provided to lock the clip in the operative position. A toe 2a of the spring clip 2 is inserted through a hole 1b in a base plate 1 with the clip 2 at right angles to its final position. The clip 2 is then turned by a suitable tool and during the turning movement the nose 2c of the clip 2 rides up an inclined surface le on the plate 1 until it reaches its final position on the rail flange 12a in which position the clip 2 is locked by a square ended tail 2b engaging a rib 1d on the plate 1. Alternatively the clip may be locked in position by a downwardly turned tail, 2<SP>1</SP>, Fig. 4A, engaging a recess 2e in the plate 1 or by terminating the inclined surface at a higher level than the rail flange 12a so that the nose 2c drops on to the flange 12a when leaving the surface 1e. The toe 2a engages in a recess 1c in the plate 1 which recess 1c may extend the whole length of the plate 1 or may be local to each hole 1b. In the hollow metal sleeper arrangement shown in Fig. 6A, inclined surfaces 21e are provided on each side of each clip 2 and a slight recess is provided in ribs 21d to lock each clip 2 in the operative position. As shown in Fig. 7 the clips 2<SP>1</SP> are formed from single lengths of spring steel and are locked in the operative position by a recess in the side of each hole 1b farthest from the rail. In a further arrangement shown in Fig. 10 the clip 2<SP>1</SP>., shaped differently from that shown in Fig. 7, is locked in the operative position by a projection, shown dotted, on the clip nose engaging a recess 21c in the inclined surface 1e. The clip may be strengthened by the addition of a tail shown dotted in Figs. 7 and 10.

Title: Motor-operated constant support hanger
IPC: F16L3/215
Filed: 1959-06-05
Abstract: 902,222. Automatic tension-control systems. GRINNELL CORPORATION. June 5, 1959 [Aug. 20, 1958], No. 19333/59. Class 38 (4). A jack operated by a motor to move a load relative to a fixed support is controlled by a switch-actuating load detector, located between the jack and the fixed support, so as to maintain a constant supporting force. In Fig. 1, piping 30 is supported by rods 24, 28 from a nut 32 in threaded engagement with a rod 36 resting on compressible disc springs 42 carried by a fixed housing 10, so that the lower end of rod 36 moves with changes of load due, for example, to thermal effects on the piping. These movements-are transmitted through a projection 52 to operate switches 48. If the load deviates beyond a predetermined extent in either sense one or other of two of the switches is operated to run an electric motor 60 in the appropriate direction to correct the deviation by rotating rod 36 through reduction gearing 58 and thereby raising or lowering nut 32. When the deviation is corrected, one or other of two more of the switches is operated to stop the motor. Nut 32 is prevented from rotating by guides 66 on fixed housing 10 and a thrust bearing 40 facilitates rotation of rod 36. Motor 60 and gearing 58 are mounted on a plate 62 which is free to move along guides 66 to follow the small movements of rod 36 due to deflection of springs 42. The piping may be secured in position temporarily by nuts and bolts 76 while the motor and jack assembly is removed for servicing through a door (not shown) in housing 10. The motor may be mounted on the fixed housing with a belt drive to the reduction gearing allowing small movements of the latter due to deflection of the springs. In a modification the threaded rod, which does not rotate, extends downwards to support the piping and is adjusted in position vertically by a nut rotated by the motor through a worm gear or belt drive, the detector springs being annular and arranged between the nut and the fixed housing. Alternatively the threaded rod may support the load and be rotated by the motor, the detector springs being located between a nut, which does not rotate, and the fixed housing. In another modification the nut supports the load and is rotated by the motor, the detector springs being located between the bottom of the threaded rod and the fixed. housing.

Title: Process for the production of foils, filaments and similar products from alkaline aqueous cellulose solutions
IPC: D01F2/00
Filed: 1930-06-25
Abstract: In the production of foils or filaments from highly viscous alkaline cellulose solutions such as viscose or cuprammonium cellulose solution, the solutions are heated to elevated temperatures prior to entry into the pouring devices or nozzles. The solutions are coagulated in the ordinary coagulation baths. The conduit through which the cellulose solution flows to the extrusion device may be surrounded by a heating jacket and maintained at a temperature of 50 DEG  C.  The conveying pump may also be provided with a heating jacket.  The process enables more concentrated solutions to be employed since the viscosity is reduced by heating, and it results in products having greater resistance to tearing.  The Specification as open to inspection under Sect. 91 (3) (a), comprises also a modification where the solution is heated in the pouring device or nozzle.  This is stated in the Specification as accepted to be disadvantageous.

Title: Improvements in and relating to a pre-payment telephone apparatus
IPC: H04M17/02
Filed: 1943-11-02
Abstract: 573,329. Automatic exchange systems. SOCECO, SOC. DES COMPTEURS DE GENEVE. Nov. 26, 1943, No. 19805. Convention date, Nov. 18, 1942. [Class 40 (iv)] The arrangement described in Specification 586,310 for preventing the effective dialling of certain numbers is applied to a prepayment substation, and the circuits provided for shunting the impulse contact include a magnet which when energized releases the connection and returns the inserted coin. The closure of the loop operates relay 169 which connects the right-hand winding of magnet 115 across the switch-hook contact 17. A coin inserted in the shoot 120 is tested by mechanism at 121 and falls on to a lever 127 which turns the shaft 128 until a pawl 137 engages a step on a cam 134, while a second cam 133 on the shaft operates contacts 135, 136, connecting magnet 159 in the loop and removing a short-circuit from the impulse contact 19. Magnet 159 energizes and releases a cam-shaft 148 which rotates by spring action into the dialling position where it is held by the engagement of a pawl 161 with a recess 162 of the cam 150. The number - discriminating mechanism is brought to its starting condition by the engagement of detents with ratchets 33, 57, this being permitted by the rotation of the cam 151, and contacts 163, 164 operated by the cam 152 place the loop under the control of relay 169 and short-circuit magnet 159. Assuming that a permitted connection is established and that the called party replies, the metering magnet 141 is operated by one or more A.C. metering impulses and releases the lever 127 by withdrawing the pawl 137 so that the coin falls into the shoot 123. When the receiver is replaced, magnet 115 energizes, being no longer short-circuited at the switch-hook contact 17, and withdraws the pawl 161 so that the cam-shaft 148 rotates to its normal position, the loop being opened at contact 165. If the call is unsuccessful, the lever 127 is not released and the rotation of the cam 154 withdraws a stop 126 to direct the coin into the refund shoot 124. If on the other hand a prohibited number is dialled, the discriminating mechanism operates as described in Specification 586,310, and after a certain number of digits, the left-hand winding of magnet 115 is shunted across the impulse contact 19 so that it is energized by the next dialling operation. The cam-shaft 148 therefore restores to normal and the loop is opened at contact 165, the coin being refunded. Should the subscriber attempt to obtain a prohibited number by first dialling the initial digits of a permitted number and then releasing the connection by a prolonged opening of the impulse contact, the loop is broken by the release of relay 169, which is sluggish in falling back and is unaffected by dialling impulses. Similarly, an attempt to use the switch-hook for impulsing brings about the operation of magnet 115.
Patent GB-147793-A (GB)
Title: Improvements in electric current controlling devices
IPC: H01H71/00
Filed: 1920-07-09
Abstract: 147,793. Apple, V. G. Jan. 17, 1919, [Convention date]. Controllers with overload and no-volt release.- Relates to a combined starting-switch and automatic current-regulator and overload and underload cut-out for use in connexion with electric starting-equipment for motor-cars. The plunger 35 is depressed by hand or foot to bring a disk 43 against two contacts 44, 45, thereby closing a circuit which connects the two six-volt batteries 66, 67 in series with the unit 65 to run it as a motor. As soon as the prime-mover has started-up, the unit 65 will be driven as a generator and a winding 32, which is connected in shunt across it through the earthing point 59, Figs. 1 and 5, will energize the electro-magnet 15. When the plunger 35 is released, it is returned by a spring to the position shown in Fig. 1, breaking the first circuit and making a new set of connexions. This places the parallel windings 33 and 34 across the poles of the generator 65 to increase the magnetic flux in the electro-magnet 15, and simultaneously connects the batteries 66, 67 in parallel across the generator for re-charging. The new circuits are made through the points 27<1>, 50 and 28', 51. The points 27', 28<1> are carried by two armatures 18. 19, which are pivoted to the upper pole-piece 16, and are normally urged away from contact with the points 50, 51 by means of adjustable springs 22. In addition, a disk 40 positively prevents these contacts from closing so long as the disk 43 is in the depressed position and the first circuit is closed. As the disk 43 rises to break the first circuit, notches 60 allow the armatures 18, 19 to swing inwards under the magnetic pull of the pole-piece 17 to form the second set of circuits through the points 27', 50 and 28', 51. Screws 25 limit the outward movement of the armatures 18, 19. Should the current increase above a predetermined value, the magnetic effect of the coils 33, 34 will draw the plunger downwards until the disk 40 acting against the inclined sides of the notches 60 forces the armatures 18, 19 outwards to break contact at the points 27<1>, 28'. The position of the disk 40 is restored by a coiled spring in the plunger. Similarly, if the current value sinks too low, the springs 22 break the same contacts. Excessive electromotive force across the generator will energize the shunt coil 32 to cause the plunger 35 to be depressed until the disk 40 again forces apart the armatures 18, 19 to break the circuit. The parts are so arranged that the second set of circuits are made through the points 27<1>, 50 and 28<1>, 51 just before the first circuit across the points 44, 45 is broken.
